TRAVERSE-MOTION FOB WINDING YARN ON BOBBINS.

Specication of Letters Patent.

Patented Feb. 4, 1913.

Application filed March 29, ,1909. Serial No. 486;304.

To all whom it may concern.-

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at 'orcester, in the county of Worcester and State of Massachusetts, have invented certain new and 4useful Im rovements in Traverse-Motions for Win ing Yarn on Bobbins, of which the following is a specificat-ion.v

My invention relates to a traverse motion for winding yarn on bobbins, and more particularly to a variable traverse motion for the yarn guide, and my invention particularly relates to improvements on the traverse motion shown and described in my pending application for Letters Patent, Serial No. 427,806.

The object of my invention is to provide means whereby the direction of movement of the yarn guide toward the butt ofthe bobbin is reversed, at a point nearest the butt of thq bobbin, during the first reciprocationI of said guide, and each successive reversing point is farther from the butt of the bobbin, the distance. between each of said reversing points andthe previous one, being less and less'as thebutt of the bobbin is built up, and until said butt has reached its full diameter, when the. distance between said reversing points becomes constant durmg the bobbin.

I have shown in the drawing a detached portion of :i traverse motion of the type shown and described in my pending application, Serial No. 427,806, .abovefreferred to, with my improvements combined therewith, sufiicient to enable those skilled in the art to understand the construction and operation of the same.

Referring to the drawing:-Figure 1v is' a front view of a detached portion of `one end of a spinning machine, with my improvements in traverse motion combined therewith, looking in the direction of arrow a,\Fig. 2. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in the direction of arrow b, same figure, and, Fig. 3 is a view of the ring rail or' yarn guide, and connection to the traverse cam.

In the accompanying drawing, 1 is a p0rtion ofthe end frame of a spinning machine, 1 is the bearing or girder for the spindle rail, not shown. A traverse up and down motion is communicated to a. vertically rethe buildingr 'up it-the remainder of ciprocating ring rail or yarn guide 4, through the connector 13 to a rocker arm 11, pivotally mounted on its lower end on a stud 8 carried on a hanger 9, and a second arm 7 also pivoted on said stud 8, and' carrying on an extension 7 a weight 10, and having a roll 7 to engage a. foot 6 on the vertically moving rod 6, connected with the ring rail 4, see Fig. 3, all in the usual way. The connectory 13 is adjustably secured by a pin 14 in an elongated lslot 15 in the upper end of a cam lever 15. The hub on the lower end of said cam lever 15 is loosely mounted 0n a stud 16 in a stand 17 secured to the frame 1.

The above mentioned parts correspond with similar parts shown and described in my said application, Serial No. 427,806.

I 'will now describe my improvements in the mechanism for communicating a traverse up and down movement to the ring rail 4, Fig. 3, or to communicate a movenient to the lever 15, connected with said ring rail or yarn guide through. the connector 13.

18 is a rotary shaft o rated from some moving part of the machine, not shown. 19 is a cam fast on said shaft, and having a cam face, in this instance on its inner end, which, in the rotary movement of said cam, engages a roll 2O on av stud 21 on a cam lever 22, which has its hub 22 fast on a rock shaft 23. To the cam lever 22 is attached one end of a helically coiled contraction spring 22". The other end of said spring 22" is attached to the frame 1, see Fig. 1. The spring 22 acts to hold the roll 20 in engagement with the cam 19.

On the inner end of the rock shaft 23, which is suitably mounted in a bearing 24 at the lower end of a stand 25, see Fig. 2', is' loosely mounted a cam 26, which has two or more holes 26 therethrough. On the in` ner side of the cam-"26 is fast a gear 27; a second gear 28 is fast on the rock shaft 23. The gear 28 has in this insta-nce one tooth less than the gear 27. A ratchet wheel 29 is loose on the rock shaft 23, and carries a stud, on which is loosely mountedy a pinion 30, see Fig. 1. The pimon 30 is of sufficient width to mesh with both of the gears 27 and 28. A washer or disk 29 extends between the ratchetwheel and the gear 28, see Fig. 2. The ratchet wheel 29 has its hub 29 provided with an annular' groove or recess therein, to receive the forked end of an arm 31, which has its hub .31 fast on a rod 32, which is loosely and sglidably mounted in a hub or lboss ,32 on thev lower. end of the stand 25, see Fig. 2. --The rod 32 has in this instance an engaging or ball-shaped end 32 to he grasped by the lhand of the operator to slide the rod 32, the arm 3l, andthe ratchet 29, thereby disengaging the teeth cient friction between saidratchet and gear,

to cause said" ratchet which is loose on the shaft 23. to be rocked with said gear 28., which is fast 0n said shaft 23,.when said shaft is rocked in the direction of arrow z,

Fig. l. bears against and is connected with the hub 34 of an arm 34; said hub 34 is loosely mounted on-the rock shaft 23. The torsion spring 33 acts to yieldingly move the hub 34 and the arm ,34 toward the right in Fig.

i 2. The #hub 34 has a ,recessed portion at 34', into which extends a pin 38 on a collar 38 secured on the rock shaft 23, in this instance by 'a set screw. The collar 38 acts to limit and adjust the 'movement of the arm'34. The arm 34 has its upper end from thefree en vIsis curved, or of shield-shape at 34, see Fig.

1, whichend is adapted to extend under and to engage a in 35 which extends out of a pawl 35 ;A the pawl 35 is suitably mounted on a. stud on a, stand or bracket, not shown. Extending out from the shieldjshaped end 3 of the arm-34, and

secured thereon, is a iattened pin or strip 34, 4which is preferably bent downwardly at its outer end and adapted to extend in the path of and to' be engaged by a stud 26, which. is loosely held in one of the holes 2.6' on the outer endof the cam 26, to move the arm with its shield-shaped end 34, more or less to ithe leftin Fig. 1, and the shoulder 34", formed by a recess 34', away from lthe pin 38', when the cam 26 is returned to the starting position by the operator, with the roll 15* on the cam lever 15,

on the lowest part of the cam 26, as shown 1n Fig. 1. Theholes 26' on the outer end of the cam 26 are forvarying-the position point for the beginnm ofthe stud 26, to cause more or less movement of the arm 34, and the shield-shaped end 34V thereon, to the left, when the cam 26 is moved by the operator to the starting of the new wind. It will be understood t at the farther the shield? is moved toward the left in Fig.

1, at the beginningof the wind, the greater the number of teeth the ratchet 29 vwill be The outer end of the spring 33v moved by the pawl 35,.until the limit of.,

above described. The spring 33 causes the strip 3 4 to remain in contact with the pin 26a and thus follow the cam 26 around the shaft 23, until the shoulder 34b remains in contact with the pin 38 on the collar 38, and the contact continues during the rest of the wind. l 1

It will be understood that by causing the shaft 23 to turn within the ratchet wheel 29, the saine relative movement between the shaft 23 and cam 26, is caused that would be caused by-'turning said ratchet wheel 29 on the shaft 23, if said shaft were at rest; that is 'the pinion 30 is revolvedabout two gears 27 and 28, rneshinfJr with the teeth of both; the gear 28being fast on the shaft 23 and having one lessl tooth than the gear 27, which is loose on said shaft. Said earv27 will be caused to rotate around the s iaft 23 a space equal to one of its teeth for every complete revolution made by the ratchet Wheel 29.

From the above description in connect-ion with the drawing, the operation of my improvements will be readily v understood by those skilled in the art.

Through the rotation of the cam 19 and the movement of thecam lever22, the rock shaft 23 is caused to rock, causing the gears 2,7 and 28, the cam 26, and the ratchet wheel 29, to rock also. The ratchet wheel 29 is 'rocked with the shaft 23 in the direction of arrow z, Fig. 1, through the frictional engagement of the gear '28 with said ratchet Wheel 29. The shield-shaped end 34 raises the pawl 35 when ythe shaft is rocked in the direction of arrow z, Fig. 1, and allows the ratchet wheel 29 to be rocked in the opposite direction by the cam mechanism, until the shield portion 34 has passed from under the end of the pawl 35', and allowed the pawl to drop down and engage the teeth on the-ratchet' wheel 29, to hold said ratchet wheel stationary for the remainder of the movement of the rock shaft 23 in that direction.

At the'starting of the winding, the ring rail or yarn guide is in its positlon nearest the butt of the bobbin, and the roll 15 on the cam lever v1 5 will be on the lowest part of the cam 26, as shown in Fig. 1. The arm 34, having the shield shaped end 34", is moved tothe left in Fig. 1, through its engagement with the stud 26'l on the cam 26, said cam being moved by the o rator in the direction opposite to that in icated by arrow z, will allow the pawl 35 to drop and a greater numberv of teeth on the ratchet Vwheel.4 29 to pass by the end of said 4pawl 35, when the said ratchet wheel 29 is'revolved in the direction of arrow z, and hold said ratchet through the greater part of the return movement of the rock shaft 23, at the beginning of the winding.

The gear 28, which is fast on the shaft 23, has in this instance one less tooth than the ear 27, and therefore the revolution of said gear 28, relative to the ratchet wheel 29, carrying the pinion with it, causes the ear 27 to gradually rotate the cam 26 in t e direction of the arrow z, Fig. 1, whereby the cam 26 will be rocked by the shaft 23 and present a constantly changing cam surface to the roll 15a on the cam lever 15, which is connected, through the rod 13, to the mechanism for communicating a traverse up and down movement to the ring rail or yarn guide 4, shown in Fig. 3. The rotation of the cam 26 causes the arm 34 and the shield-shaped end 34" thereon, to gradually move to the right in Fig. l, until the pin 38 on the collar 38 engages the notch 34 on the hub 34. The stud 26 may be adjusted or placed in any one of the holes 26', to vary the position of the shield 34', and cause more or less movement of said shield through the pin 34,

It will be understood that the details of construction of my improvements varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a traverse motion for winding yarn on bobbins, a rock shaft, means to communicate rocking motion to said shaft, a cam loose on said shaft, a ratchet wheel yieldingly held on said shaft, a pawl, a pawl -shield connected to, said shaft, and connections intermediate said cam and said shield, to regulate the relative movement between said ratchet wheel and said shaft.

12. In a traverse motion for winding yarn on bobbins, a rock shaft, a cam loose on said shaft, means to operate said rock shaft, a ratchet Wheel on said rock shaft, means to rock said ratchet wheel with said shaft in one direction, and a device to hold said ratchet wheel at rest during a portion of the Areturn movement of said rock shaft, and means to automatically regulate the engagement of said device with said ratchet.
